Analogue Import Problems on FCP and Decklink

I know this is possibly a Decklink problem so I have posted on the Blackmagic forum as well
But thought I'd give it a go on here as lots of you have Decklink HD cards and it takes a while to get a response over there....

I posted this problem a few months ago and still isn't cured.
I have problems capturing analogue material through the Decklink Extreme HD card into FCP
I get lots of lines and interference on the preview monitor on FCP and thats what it records
I replaced the card and still the same
I connect a DVD player or Beta SP directly to the Decklink input, ie bypassing my router/switcher and still the same interference.
My last resort was to connect my DVD player to the HDMI input and I can't get that working at all !!
I change all the settings in the Decklink preferences, restart, load new drivers, go back to old driver and still the same problem.
I have moved the card to another slot in my Mac Pro
I can't believe its a problem with the seating of the card or the MAc as the SDI input works perfectly.
Obviously I am now desperate to get this fixed with a large job next week involving importing dvd's etc.

Well I just find it easier to grab selections from the DVD that way, the macro protection cant be the problem because it used to be fine, and yes, same problem importing Beta SP and yesterday a VHS ( yes really !! )

Hi paul,
The DVD you never know, but you shouldn't have problems with the Betacam at all.
That should work with a "Black Burst" or even without any kind of reference. The very "Video IN" should be enough.
I would recommend you to try to fix the Betacam capture first, then you may try to pass the DVD signal through the Betacam.
I gave up long ago working with BM due to the problems to get a good connexion. The big black cable made my life really miserable; I had to fixit every 5 minute to get my picture in the monitor.
Best,
